Can someone explain to me how exactly can JavaScript measure processor cache access latency? Also, isn't the performance of inactive tab supposed to be throttled?
- gowld 8y agoIt's not a direct measurement, but a program can request an action ("get data from a website") and measure how long it takes. Short time implies cached.
